Hi Dan,

Thanks for quick response. Even with these compiler flags, we get the same result. On the same page there is this:

"RtAudio Hang on Exit in 0062
"RtAudio will hang on app exit in OF 0062. The only way to fix this is to make a small edit to the OF 0062 core by "editing lib/openFrameworks/sound/ofSoundStream.cpp and commenting line 143 so close() is not called."

I'm not entirely sure which version we're using, but the ofSoundStream.cpp file is only 140 lines long.
If we upgrade to the latest ofxPd, will it still work with OF 6.2?
Cheers,
Ed
